Patented Sept. 17, 1929 Aiuurrto STATES PATENT OFFICE Aniaimstr CLYDETAYLOR AND DAVID BARCLAY MACKIE, oF SACRAMENTO, CALIFORNIA COMBINED RODAND GUN Application filed February 28, 1928. Serial No. 257,654.

ur invention relates to improvements in rods and guns combined, and itconsists of the combinations, constructions, and arrangementshereinafter described und claimed.

Persons who spray trees, hedges, and the like, for killing insectsinhabiting the same,

usually carry with thema spray rod and al spray gun. These are twodistinct imple ments, and are `for two particular'kinds of work. Therodpermits the sprayer to place the device in a position for spraying ytheunderside of the leaves ot' low shrubbery, with ease, aud this samerodcan be used for spraying up to a height of siX feet. For any pointhigher it is necessary to use a gun. A gun cannot be usedeflicientlyunder six feet without yplacing` it close yto the `ground.This causes the operator to bend or kneel upon the ground in. order tospray, the under-sides of low leaves. Ifthis is not done, hey iscompelled to change toa rod. f

The principal object of the present in vention is to combine a sprayrodand gun for accomplishing both kinds otwork with the same device. Therod makes use'rof two spray nozzles that are inclined with respect toeach other for directing a stream upwardly at an angle ot 450 whenk therod is held in a vertical position. The rod emits a line stream. that isnot injurious to foliage. It' the gun were used close to the foliage, aswould be necessary for work close to the ground, the stream issuing fromthe gun would injure the blossoms, fruits, or leaves, because thisstream is more coarse than the stream thrown out by the rod. Vetheretore use a device which makes use of the rod principle for workclose to the ground and makes use of the gun principle for workextending siX feet or more above the ground. The gun can ellicientlyspray trees up to a height of seventy feet.

i/Ve have Yfound that when these two devices. are combined, a length oflive feet over all is ample and providesy a device which best meets theneeds for all kindsof work. The combination rod and gun does away withthe necessity of the operator first using one instrument and' thenkusing the other, and also does away with thenecessity oit carrying twodevices to the place of Work. The deviceyfurthermore saves Atime whenchanging frein one to the other, as they rod is designed toautomatically shut off when l the operator releases the actuating leverand.

grasps the controlhandle for the gun.

A further object ot our invention is to provide a device of the typedescribed which is simple in construction and which can beusedfeiiiciently rin spraying anything from the'ground up. y

@ther objects, and advantages will appear in the followingspecitication, and the novely features of the device will beparticularly pointed out in the appended claim. a

k(iur invention`r is illustrated in the accompanying drawing forming apart of this application, in which l: y f i .Figure .l is a rearelevation of the device; rFigure 2 vis a section along the line 2-2 oitFigure l; and i Figure 3 is atransverse section through thegun-actuating shaft. f f

In carrying out'our invention we provide a tubular casing l that formsthe ym'ain body of the gun. A T- 2 is secured to the casing l, and thismay be connectedto a hose that delivers the insecticide tothe gun..

`A gun head 3 is mounted at one end of the casing l, and a controlhandle 4 is mounted at the other end. A control shaft 5 extendsthroughout the lengtliof the casing l and is secured to the handle 4 bynuts 6. The handle is threaded upon a screw 7, and this screw in turn isintegral with' a packing nut 8. This nut seals the lower end of thecasing 4l. A rotation of the handle 4 upon the screw 7. ,will movetheshaft 5 longitudinally within the casing. n n I y Thehead 3 of the guncarries a cap 9, and,

this cap encloses a whirling plate l0. y The plate l0 yiscarried by thehead 3 and bears yagainsta head ring 11. The upper end of jacent to thevalve 12 and prevent the Whirling of the iiuid within the casing 1 justprior to its entrance into the head 3. lVhen once the iluid enters thehead 3, it is subjected to a whirling action by the plate 10; The amountof fluid flowing out from the head 3 is controlled by the handle 4f andthe valve 12.

The casing 1 has a by-pass 15 that com-k municates with a spray rodindicated generally at 16. Thev rod 16 has a casing 17 in which a valve18 is mounted. rlhis valve is spring-pressed and is normally held inclosed position by a. spring 19. A plunger shaft 2O extends from thevalve 18 and is connected by means of a wire 21 to a spray rod lever 22.The lever is pivoted at 23 to the casing 1, and the wire 21 is enclosedfor the greater part of its length in a tube 24.

Figure 1 shows how the spray rod 16 branches into a Y and how each leg25 of the Y terminates in a spray nozzle 26. The spray nozzles areinclined at 45 with respect to the longitudinal aXis ot the leg 25 for apurpose hereinafter described.

From the 'foregoing description of the various parts of the device, theoperation thereof may be readily understood.

When using the device as a spray rod, the valve 12 is closed and thelever 22 is manipulated for allowing as much fluid as desired to flow'from the nozzles 26. The nozzles are of standard construction and aretherefore not shown in detail. They are designed to emit a line spraystream that will not injure delicate plants even when the nozzle isbrought very close to the plants. The operator can hold the casing 1 ina p0- sition for causing the nozzles 26 to direct the spray upwardlyagainst the underside of the leaves. rllhis is the place where theinsectsl lay their eggs, The casing is short enough to readily permitthis operation, and the nozzles 26 are inclined at the right angle toobviate the necessity of the operator kneeling down upon the ground whenusing the rod. l

After the shrubbcry has been sprayed to a height of six feet and it isdesired to spray still higher, the lever 22 is released and the valve 18will instantly close. yEhe handle 4l may now be manipulated for movingthe valve 12 into open position. When this valve is backed oil' from itsseat, a slight distance, the material is forced through the whirlingplate and a mist is thrown fromy the gun whichv spreads over an area ofabout three to four feet. When the valve is backed up a little further,the area covered by the mist is not so great, but the gun has a longerrange. A gradual backing up of the valve, until it is completelydisengaged from the valve seat and also from the whirling plate, willcause the whirl to disappear from the stream issuing from the gun head,

and the stream will be ejected with suflicient force to carry it alconsiderable distance into the air, i. e., a distance of seventy feet.rlhe long tins 14 not only act as guides for the rod 5 but also take thewhirl out of the water. The force or" the stream passing through the airfor this distance breaks it up into a. spray before the liquid reachesthe article t0 be treated. This steam is suflicient to reach the tops oftall trees. As heretofore stated. two fins 1l are used for preventingthe whirling of the fluid until it strikes the plate 10. rllhe device isextremely simple in construction, and provides a novel manner ofcombining a gun with a spray rod.

Although we have shown and described one embodiment of our invention,'itis to be understood that the same is susceptible of various changes, andwe reserve the right to employ such changes as may come within the scopeof the appended claim.

We claim:

A combined spray rod and gun comprising a tubular member,agun nozzleplaced at one end of said member, a valve for controlling the flow ofwater through said nozzle, a handle disposed at the opposite end ot saidtubular member for controlling the movement of the valve, a spray nozzlehaving its axis inclined with respectto the longitudinal axis ot thetubular member, said nozzle being in communication with and supported bysaid tubular member, a manually-controlled valve for controlling theflow of fluid through said spray nozzle, and a fluid inlet pipe for saidtubular member for delivering fluid to the gun or the spray rod.
